80. Megaristerus mandibularis, N. 



M. piceo-niger, leviter metallescens, subtus brunneus, antennis, tibiis 

 tarsisque testaceis, ore brunneo. Long. corp. 1^-2 lin. 



Capite inter antennas 2-foveolato, mandibula sinistra robustissima 

 porrecta, dextera mediocri labro obtecta; thorace basi 2-foveolato, 

 linea longitud. utrinque abbreviata media diviso, antice lunate im- 

 presso ; scutello majore ; elytris obsolete striatis, striis juxta suturam 

 distinctioribus, cum thorace parce subtiliterque punctulatis, inter

Prope Colombo rarus. 



81. Megaristerus stenolophoides, N. 



M. brunneo-piceus, elytris obscurioribus metallescentibus maculis 4 

 flavis, raargine sutureeque apice brunneis, pedibus, antennarum 

 basi palporumque apice pallide testaceis, ore, mandibulis brunneis 

 exceptis, testaceo. Long. corp. 1^ lin. 



Prsecedenti similis, corpore robustiore minus depresso et colore 

 facile tamen distinguendus. DirFert prseterea palpis max. art. 4° 

 minus distincte, lab. eodem fortius truncato ; thorace magis trans- 

 verso, basi obsolete ruguloso ; elytris profundius striatis, puncto ad 

 striam 2 m fere obsoleto, cum thorace haud punctulatis, maculis 4 

 subobliquis flavis ; 2 humeralibus in interstiths 5°-6°, 2 subapicalibus 

 in interstitiis 3°~4°.

 tulisque 2 subapicalibus flavis, subtus brunneus, tibiis tarsisque 

 testaceis, antennarum basi oreque brunneo-testaceis. Long. corp. 

 1 1 lin. 



Differt a M. mandibulari mandibula sinistra altera vix robustiore, 

 elytris infra humeros inter marginem et striam 2 m macula obliqua 

 intus angustata ante apicem in interstitio 3° pustula parva flavis, 

 apice fortius quam in prsecedente rotundatis.
